bowenite

Bowenite is a translucent to opaque variety of serpentinite, a rock composed primarily of serpentine minerals. It is typically pale green to white in color, often with a waxy or greasy luster. The name bowenite honors George Bowen, a mineral collector from Rhode Island.

This mineraloid is a dense, compact stone that can be polished to a high sheen, making it suitable for ornamental objects and carvings. Historically, bowenite has been used for tools and decorative items in various cultures. Its composition often includes minerals like antigorite, lizardite, and chrysotile, which contribute to its characteristic green hues and texture.

Bowenite is found in several locations worldwide, with notable deposits in China, New Zealand, and the United States. Its hardness is relatively low, typically around 3.5 to 4.5 on the Mohs scale, which makes it susceptible to scratching but also workable for carving. While not a gemstone in the traditional sense due to its softness, its attractive appearance and workability have led to its use in jewelry and decorative arts. The term bowenite is sometimes used interchangeably with nephrite jade, as some bowenite can exhibit properties similar to jade, though it is chemically distinct.
